11:27-33 Our Saviour shows how near akin his doctrine and baptism were to those of John; they had the same design and tendency, to bring in the gospel kingdom. These elders did not deserve to be taught; for it was plain that they contended not for truth, but victory: nor did he need to tell them; for the works he did, told them plainly he had authority from God; since no man could do the miracles which he did, unless God were with him.And say unto him, by what authority dost thou do these things?.... Enter into the temple, as if he was Lord of it; and correct in such a magisterial way every thing he thought an abuse in it; do the miracles he did, as healing the lame, and blind; and take upon him to instruct the people, a work he was now engaged in:

and who gave thee this authority to do these things? See Gill on Matthew 21:23.
